Raptor,

I have been toying around witht he idea of building the Millenium Falcon, as a lifting body, but never got round to it. Along the way I found that the X-Wing hase been built and flown, so I think you do have a good chance of making this fly. Although of course, it may not be perfectly to scale.

IF its close to scale, it willprobably be a "hot" flyer, with high stall speed, unless you build it really really light. Just my opinion.

Good luck with this project, hope to see it flying succesfully
